# §4373. Unit cost reports: immediate report from program manager to service acquisition executive upon breach of significant cost growth threshold


If the program manager of a [major defense acquisition program](/usc/10/3042.md) for which a unit cost report has previously been submitted under [section 4372 of this title](/usc/10/4372.md) determines at any time during a quarter that there is reasonable cause to believe that the [program acquisition unit cost](/usc/10/4371.md?p=a-1) for the program (or for a designated major subprogram under the program) or the [procurement unit cost](/usc/10/4271.md?p=b-1) for the program (or for such a subprogram), as applicable, has increased by a percentage equal to or greater than the [significant cost growth threshold](/usc/10/4371.md?p=a-2); and if a unit cost report indicating an increase of such percentage or more has not previously been submitted to the [service acquisition executive](/usc/10/101.md?p=a-10) designated by the [Secretary concerned](/usc/10/101.md?p=a-9), then the program manager shall immediately submit to such [service acquisition executive](/usc/10/101.md?p=a-10) a unit cost report containing the information, determined as of the date of the report, required under [section 4372 of this title](/usc/10/4372.md).
